Help! 1st DIY rigg

first off hello,
the skeleton is not good for that build, no you dont really need extra cooling but it cant hurt, and instead of that psu and case, look at this combo deal.

it is wayyyy better and saves you some money too.   also, get the 300 GB version of the raptor and then you can just forget about the 320 gb barracuda. or get an ssd, if you want to spend the extra money. also that motherboard is not compatible with your build (just caught that) consider getting:

ASUS P6T6 WS Revolution with NF200 3xPCIe true x16 LGA 1366 Intel X58 ATX Intel Motherboard

or

ASUS P6X58D Premium LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

those two are great, but you can go a bit lower end too.lastly, the ram isn't triple channel, so get
G.SKILL 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Triple Channel Kit Desktop Memory Model F3-10666CL7T-6GBPK

now everything should work and work well.  

I'll start with what I'm not too keen on. Sound cards. I think the general consensus is that onboard sound is usually good enough. I'm sure someone will be able to give a more solid response to that.

You want a 6gb (3x 2gb) kit to make use of triple channel. This is an affordable Tom recommended kit:

Going with the skeleton is really up to you. Personally, I don't think it's worth it unless you plan on benchmarking parts or swap components frequently. This is $5 more (after MIR) http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Also, newegg has a promo code for this similarly priced case, making it cheaper:

You don't need a 850w psu for a single 5870. You could probably even get by on a brand named 750w if you ever wanted to crossfire in the future. If not, consider:

Also, VRs are outdated. You can save from buying 2 HDs with a single:

Concerns:
1. No.
2. If you're set on that specific psu, its an excellent one.

3. Preference.

I wouldn't do the skeleton unless you like cleaning dust and swapping stuff every other day.

The Antec 1200 w/ CP-850 PSU is an unbeatable combination...you don't need 850 watts but it costs the same as many good 650/750 watters and will let you Xfire down the road.

This MoBo has SATA 6 and USB3, quoite futureproofed

Grab a Spinpoint F3 or Seagate 7200.12

If you can grab one of these, it's hot !
